I´m developing a simple reactive programming script example to download images from a web, but when I execute the script in VScode I do not get any type of output, I already tried creating a VirtualEnv

In the terminal i get this output:

CodePudding user response：

Add this to the bottom, outside of the class

theobj = asyncio.run(App().main())
theobj()

The script should work after, with some errors.
